The 40 IP is one of Tiffin's most complete Allegro Bus layouts, pairing a rear King bed with a bath and a half, a rear full bath with dual vanity plus a half bath up front, so no one's waiting in line in the morning. The Cummins L9 450HP diesel engine and PowerGlide XC chassis earn consistent praise from owners for delivering a smooth, Lexus-like ride, and the Aqua-Hot 450D hydronic system means heat and hot water without waiting for a tank to warm up. Inside, the Spyder multiplex control system puts touchscreens throughout the coach, the fireplace adds a residential feel, and a pull-out countertop gives you workspace when you need it. A washer/dryer prep, outdoor entertainment center, and ottoman round out a floorplan that's clearly built for extended time on the road.
